• The Diamond
  of Possibility
  
  by  Keith Allen Korcz

  “We symbolize logical necessity with the box () and logical possibility with the diamond (). 
  I first discuss combining negations with the box and diamond, noting
  that logical possibility and logical necessity are inter-definable with
  the help of negation: p = ~~p and p = ~~p. Thus, possibility and necessity are two sides of the same coin.”
  

  And what do we           
   symbolize by  ?
